Apply the patching material with a putty knife to small areas of wall damage no more than 12 inches in diameter. Drywall repair compound begins to harden when the package is opened, so seal the lid after scraping out some of the material with the putty knife. Let the repair dry for at least eight hours.
Sand the area with fine grit sandpaper and wipe with a paper towel to remove the residual repair compound.
Arrange a painting drop cloth on the floor beneath the repaired drywall.
Paint the entire wall with a roller brush. If the repair is large, consider using a dark color paint to help camouflage the botched drywall. Darker colors help conceal the shadows caused by irregular surfaces in the botched drywall.

Hammer a picture hanger above the botched drywall to hang pictures or posters over large areas of damage. Use a picture hanger rated to withstand the weight of your framed print or poster.
